(7%) Problem 7: In order to measure the properties of a battery, several resistors are connected to the battery in series and the terminal voltage is measured. In the first case, the resistor has resistance R/ = 5.5 $2 and the terminal voltage is AV) = 3.4 V. In the second case, the resistor has resistance R2 = 79 $2 and the terminal voltage AV2 = 9.5 V.
